Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31494634, here are decompositions:

23 + 31494611 = 31494634
53 + 31494581 = 31494634
131 + 31494503 = 31494634
137 + 31494497 = 31494634
167 + 31494467 = 31494634
191 + 31494443 = 31494634
233 + 31494401 = 31494634
491 + 31494143 = 31494634

Showing the first eight; more decompositions exist.
